1303773 V. INSTRUCTION DESCRIPTION (2) '-^' --* The main purpose of the present invention is to provide a data input device that uses a digital camera to capture an image touched by an input area to identify whether the user performs an input action. Increase the correctness of the input data. Another object of the present invention is to provide a data input device which can further utilize a vibration sensor or a microphone to detect a sound emitted when an input area is touched, thereby improving the accuracy of the judgment input operation. Another object of the present invention is to provide a data input device which has a relatively simple structure and can save manufacturing costs. Other objects, functions, and embodiments of the present invention will be described with reference to the drawings, and the details are as follows. [Embodiment] Please refer to Figure 1. The data input device of the present invention mainly includes a microprocessor 10 electrically connected to the first digital camera U, the second digital camera 12, the vibration sensor 13 and an image generating device 14 for projecting for the user. Input operation image 20; - mirror 15 is placed in the second digital camera 12, so that the second digital camera 12 can capture the image reflected by the mirror 15; a light source 16 is used to provide the first digit Camera 丨丨, second number: ^ Camera 1 2 The brightness required to capture the image.

1303773 V. INSTRUCTIONS (3) The relative position of the second digital camera 丨 2, the mirror 丨 5 and the image 2 凋 is adjusted so that the horizontal optical axis of the second digital camera 12 is parallel to the projection surface of the image 2 ,, so that the second The digital camera 12 can only capture the reference image 30 of the image 2 〇 to a very short distance above it, as shown in (9). Since the second digital camera 12 can only capture the input pen image 2 2 within a short set distance range above the keyboard image 21, if the input pen 2 2 leaves the keyboard image 2 1 and f exceeds the set distance, the second digital camera 12 That is to say, the key can not be the image of the pen 2 2, so it is possible to confirm whether the user performs the input operation correctly. The first digital camera 12 and the mirror 15 are designed to take in a reference image of a user's input operation on the image 20 by using a finger or an stylus 22 to determine whether the user performs an input operation. If the microprocessor 10 detects that the second digital camera 12 picks up the reference image of the user touching the image 2, the microprocessor 10 generates a corresponding image according to the input image captured by the first digital camera. Input signal, at this time, the bottom end of the image input pen 2 2 contacts the input area 2 2 1 of the keyboard image 2 1 . For example, when the first digital camera 11 captures the input image of the input pen 2 2 and the T ” input area 2 11 , the microprocessor 1 generates an input signal of a T, “T” word. The first digital camera 11 The second digital camera 12 constitutes a photographing device for taking in an input image and a reference image which are input by the user using the finger or the input pen 22 to perform an input operation on the image 20. " The input pen of the present invention using the second digital camera 12 The image 22 can provide the microprocessor 10 to confirm that the input pen 22 touches the horizontal position of the keyboard image 21, and then captures the image of the input pen 2 2 via the first digital camera 11 to provide

Page 7 1303773 V. INSTRUCTION DESCRIPTION (4) The microprocessor 10 confirms that the input pen 22 touches the vertical position of the keyboard image 21, and can quickly confirm that the input pen 22 is in contact with the input area 2 11 of the keyboard image 21. In turn, the corresponding output information can be generated more quickly. Inputs can be quickly generated without the need for a processor with high-speed computing capabilities. The vibration sensor 13 of the present invention can sense the vibration generated by the user's finger or by touching the image with the input pen 22. When the microprocessor detects the signal from the vibration sensor 13, it can confirm that the user performs the data input operation, according to the image taken by the first digital camera 11, or according to the first camera 11, the second digit. The image taken by the camera 12 generates a corresponding input signal. The vibration sensor 13 has a function of assisting in confirming whether or not the user touches the image and performs an input operation. Replacing the vibration sensor 丨3 with a microphone also achieves the same function. The first digital camera 1 1 and the second digital camera 1 2 may be a CCD digital camera or a CMOS digital camera. The invention can utilize the light source 丨6 having a specific illuminating color, and illuminate the finger or stylus 22 when the user inputs the operation, so that the first digital camera 11 and the second digital camera 12 pick up the finger or the input pen 2 2 . The image has a specific color and is more recognizable. In the present invention, the first digital camera 11 and the second digital camera 12 can also be combined with the filter covers lu and 121 of the same color as the light source 16 to make the image of the finger or the input pen 22 more free from ambient light. The impact of harm. The present invention can also cause the image generating device 14 to project a brighter ray Y to generate the light source 16. The image generating device 14 can also be caused to project a relatively bright light. Insulation care a Please refer to Figure 3 A, 3B. Data input of the second embodiment of the present invention
